I agree that words like simply and just should not be used in documentations, but are people really getting upset about it? I couldn't imagine being this fragile
Think a little harder, then. It was written for a reason. They even bought a domain and hosted this one page, for a reason. You think they did all that because they were fragile?
People who try to make something easy by force of "magic words" is pretty common in the tech industry.
People who write the docs likely do not want the reader to feel stupid.
This is low hanging fruit and good advice. No one is screaming or fragile here.
